Still figuring this platform out so hopefully this comment works.

Think of a comissioned painting. The artist is paid fairly once for that painting and then they never get money for it again. Copyright doesn't protect them so much as it protects those that can use their excess capital to horde things. Art has been around forever, copyright is new. Bands that make great music will be paid to perform, actors paid on set, writers as comission or sallaried. None of this needs copyright. Hell, the rise in free community/patron sponsored content like khan academy, most podcasts, and even some music artists proves we don't need copyright even in a system where it exists.
